Application of stepper motor stall detection technology in the automotive industry

Stepper motor stall detection technology is the key to ensure the safety and reliability of motor control systems, especially in the automotive field. Nanochip's driver chips, such as NSD8381 and NSD8389, have efficient stall detection functions and are widely used in scenarios such as automotive headlight stepper control, thermal management system electronic expansion valve drive, and HUD position adjustment. Both chips support high current and multi-segmentation modes, and have a variety of attenuation mode options to meet different needs. They also integrate a variety of protection functions, including bus undervoltage protection, overcurrent protection, temperature alarm, and overtemperature protection.
